Service interruption via firmware resource exhaustion
Published Aug 11, 2021 · Updated Aug 3, 2024
Uncontrolled resource consumption in Intel Ethernet 800 Series firmware before 1.5.3.0 allows local users to interrupt service. Intel identifies firmware resource consumption as the failure but has not published the resource, trigger, or code path that becomes exhausted. Exploitation requires local access and high privileges, and the documented consequence is adapter availability loss without confidentiality or integrity impact.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
